I've pretty much ignored the whole webfinger / acct: / SWD discussion (too much!). However, since it's apparent it may soon become Real, I had a look. In a nutshell, my initial reaction is "It's Not Nearly As Bad As I Thought It Would Be." :) With that in mind, a few questions / comments (I'll resist going into editorial matters, for the time being): * First and foremost, why use host-meta? What value does adding this extra step to the dance bring, beyond "We've defined it, therefore we must use it?" As I think I've said many times before, the whole point of a .well-known URI is to group like uses together, to avoid having a "dictionary" resource that gets bloated with many application's unrelated data, thereby overburdening clients with too much information (especially when they're constrained, e.g., mobile). As such, host-meta is a spectacularly bad example of a well-known URI. Defining a end-all-be-all well-known-URI kind of removes the point of having a registry, after all... Instead, why not just define a NEW well-known URI for user data? That has a more constrained scope, and saves one round trip (or more). E.g., GET /.well-known/webfinger?user=bob%40example.com HTTP/1.0 Host: example.com I.e., let webfinger define the URI template to use. Yes, some implementations might want to come up with crazy URIs, but is that really a problem we want to solve? Astute observers will notice that this approach removes the need for an ACCT URI scheme (at least here). * What's the fascination with XRD and JRD? These specifications seem to be creeping into IETF architecture; first it was in a pure security context, but now folks are talking about using them in a much more generic way, as a cornerstone of what we do. As such, I think they deserve a MUCH closer look, especially since we're defining things with "Web" in their name when the W3C has already defined solutions in this space.
